subfuzion/vote-worker repository overview

⁠worker service

This is a simple worker service that reads votes that have been pushed to a queue and stores them to the database.

⁠Testing

The easiest way is to test using Docker Compose.

⁠Testing with Docker Compose

The following will build an image for running the tests under test/test.js and then start the environment declared in ./docker-compose.test.yml.

$ docker-compose -f ./docker-compose.test.yml run sut

If you make changes to any of the Node.js sources, rebuild the test image with the following command:

$ docker-compose -f ./docker-compose.test.yml build

To view logs, run:

$ docker-compose -f ./docker-compose.test.yml logs

When finished with tests, run:

$ docker-compose -f ./docker-compose.test.yml down

⁠Stopping a worker

The worker process handles the SIGTERM (and SIGINT) signal to gracefully write votes pulled from the queue to the database before closing connections.
